Abstract (en)
[origin: TW200417648A] The object of the present invention is to provide a drum-type washing machine that can presume clothes volume to high degree of accuracy. The solution of the present invention is that a microcomputer for control that drives a motor for rotating a drum of the washing machine in a vector control manner by an inverter circuit. When the rotational speed of the motor is within a lower reference speed Nb and an upper reference speed Na, the variation of a vector-controlled q-axis current value is detected (step S4). When the variation level is below a predetermined value (step S5, "YES"), the motor is accelerated by the maximum torque (step S8) and deducing the amount of laundry on the basis of the q-axis current value of the vector control during the acceleration period of time (steps S9-S13).
